We currently have a problem that SELinux policy is being enforced when creating debugfs files. If a debugfs file is created as a side effect of doing some syscall, then that creation can fail if the SELinux policy for that process prevents it. This seems wrong. We don't do that for files under /proc, for instance, so Bruce has proposed a patch to fix that. While discussing that patch however, Greg K.H. stated: "No kernel code should care / fail if a debugfs function fails, so please fix up the sunrpc code first." This patch converts all of the sunrpc debugfs setup code to be void return functins, and the callers to not look for errors from those functions. This should allow rpc_clnt and rpc_xprt creation to work, even if the kernel fails to create debugfs files for some reason. Symptoms were failing krb5 mounts on systems using gss-proxy and selinux. Fixes: 388f0c77 "sunrpc: add a debugfs rpc_xprt directory..." Cc: stable@vger.kernel.org Signed-off-by:Jeff Layton <jeff.layton@primarydata.com> Acked-by:

alloc_init_lock_stateowner can return an already freed entry if there is a race to put openowners in the hashtable. Noticed by inspection after Jeff Layton fixed the same bug for open owners. Depending on client behavior, this one may be trickier to trigger in practice.

alloc_init_open_stateowner can return an already freed entry if there is a race to put openowners in the hashtable. In commit 7ffb5880, we changed it so that we allocate and initialize an openowner, and then check to see if a matching one got stuffed into the hashtable in the meantime. If it did, then we free the one we just allocated and take a reference on the one already there. There is a bug here though. The code will then return the pointer to the one that was allocated (and has now been freed). This wasn't evident before as this race almost never occurred. The Linux kernel client used to serialize requests for a single openowner. That has changed now with v4.0 kernels, and this race can now easily occur.

Second are fixes to the common clock divider type caused by recent changes to how we round clock rates. This affects many clock drivers that use this common code. Finally there are fixes for drivers that improperly compared struct clk pointers (drivers must not deref these pointers). While some of these drivers have done this for a long time, this did not cause a problem until we started generating unique struct clk pointers for every consumer. A new function, clk_is_match was introduced to get these drivers working again and they are fixed up to no longer deref the pointers themselves" * tag 'clk-fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: ASoC: kirkwood: fix struct clk pointer comparing ASoC: fsl_spdif: fix struct clk pointer comparing ARM: imx: fix struct clk pointer comparing clk: introduce clk_is_match clk: don't export static symbol clk: divider: fix calculation of initial best divider when rounding to closest clk: divider: fix selection of divider when rounding to closest clk: divider: fix calculation of maximal parent rate for a given divider clk: divider: return real rate instead of divider value clk: qcom: fix platform_no_drv_owner.cocci warnings clk: qcom: fix platform_no_drv_owner.cocci warnings clk: qcom: Add PLL4 vote clock clk: qcom: lcc-msm8960: Fix PLL rate detection clk: qcom: Fix slimbus n and m val offsets clk: ti: Fix FAPLL parent enable bit handling

The ARM architecture allows the caching of intermediate page table levels and page table freeing requires a sequence like: pmd_clear() TLB invalidation pte page freeing With commit 5e5f6dc1 (arm64: mm: enable HAVE_RCU_TABLE_FREE logic), the page table freeing batching was moved from tlb_remove_page() to tlb_remove_table(). The former takes care of TLB invalidation as this is also shared with pte clearing and page cache page freeing. The latter, however, does not invalidate the TLBs for intermediate page table levels as it probably relies on the architecture code to do it if required. When the mm->mm_users < 2, tlb_remove_table() does not do any batching and page table pages are freed before tlb_finish_mmu() which performs the actual TLB invalidation. This patch introduces __tlb_flush_pgtable() for arm64 and calls it from the {pte,pmd,pud}_free_tlb() directly without relying on deferred page table freeing.

sparc:allmodconfig fails to build with: drivers/built-in.o: In function `platform_bus_init': (.init.text+0x3684): undefined reference to `of_platform_register_reconfig_notifier' of_platform_register_reconfig_notifier is only declared if both OF_ADDRESS and OF_DYNAMIC are configured. Yet, the include file only declares a dummy function if OF_DYNAMIC is not configured. The sparc architecture does not configure OF_ADDRESS, but does configure OF_DYNAMIC, causing above error. Fixes: 801d728c ("of/reconfig: Add OF_DYNAMIC notifier for platform_bus_type") Cc: Pantelis Antoniou <pantelis.antoniou@konsulko.com> Signed-off-by:
